Yeah, it's nothing too special. 100% identical to the PCE game. Only difference is that it runs in 640x480, so depending on your monitor/tv it might look better then when played on a PCE. It runs totally fine for me in Win 7 64bit. You just need to run the installer in compatibility mode and the game will only run in 256 colors.
Price wise, it pops up here in Japan often enough and usually goes for $100 or so.
